http://www.shapeways.com is a link a friend on another list passed my way.
Ive never used it so i can speak for their products.
Kelly, i plan on cad'ing some stuff up just for my own personal project
notes in an attempt to make some progress on it.
What is 11" EIR? For sprocket cutting I would think some sort of pointy cog
system would work well if you keep the tension on the film high. I have no
idea, never made one.
Jas, it should also be noted that not all 110 film cameras use the sprocket
to cock the shutter. Just a lot of them. :)
